A few problems with server code

[neubig]

In trying to run the server code, I found a few problems:

1. First, parts of the command seem to assume you're in the server directory and parts assume that you're in the top directory. The following command worked for me from the top directory:

   PYTHONPATH=. python server/app.py --config_file config/server/config_py3.json

2. There are some package requirements that are not specified anywhere. I was able to fix them with the following command, but it'd probably be good to add them to the conda environment:

   pip install flask python-rex

3. I got stuck on this bug, which prevented it from working on atis: missing data in atis #9

I can fix the first two and send a PR, but the second one I'm not sure where to get the requisite file. For the time being I'll try to work around this by disabling atis in the server.

One more problem:

4. While I was able to set up a server and get results by accessing http://server.name.cmu.edu:8081/ I'm not able to successfully access http://server.name.cmu.edu:8081/parser/conala/print%20hello . It gives me a 404...

Thanks for reporting this! For 4., the correct URL it should be:

http://server.name.cmu.edu:8081/parse/conala/print%20hello

Try: http://moto.clab.cs.cmu.edu:8082/parse/conala/print%20hello
